activity 之間值傳遞

---

如何在activity之間傳遞對象

 

• 傳遞端

Intent intent = new Intent();
intent.setClass(Login.this, MainActivity.class);
Bundle bundle = new Bundle();
bundle.putSerializable("user", user);
intent.putExtras(bundle);
this.startActivity(intent);

• 接收端

Intent intent = this.getIntent(); 
user=(User)intent.getSerializableExtra("user");

 

• 將傳遞的類對象繼承序列化
